yes and no. it depends on the plant,grow medium, ph,. but yes for a basic rule of thumb more pk in flower and slightly less N. only slightly. you have to be light on calcium intake in seedling/veg and then be more heavy once you see more than a few hairs. but still have some N in there. it does wonders to bud size as well. basically anything you do to a photo can be done to an auto as far as nutes go BUT
you can not (should not) top it or try to cut it in any way
you can not clone an auto
and most autos are kind of nute sensitive. though im experiencing one that eats more than a photo right now. i have a grow journal going if you wanna see..
that being said if you follow a nute schedule for a normal strain. just go by a 1/4 of what they say to start. and experiment from there..
